My iPhone recently turned one and a half, and let me tell you, the battery isn't what it used to be. The battery life isn't terrible, but it's certainly flagging. For folks with old smartphones, you know the feeling: you want a safety blanket so you're not left without your communications hub at the worst time. This tiny Mophie Juice Pack seems like it would fit the bill: it's a portable 2000mAh battery so you can give your gadgets a little boost. Mophie makes good products — Mario Aguilar relied on a (larger) Mophie juice pack to get through CES. Plus, with this model, the actual battery is tiny, and today, there are two cool sales on it.

Usually the 2000mAh Mophie Juice Pack Boost sells for between $40 and $50, but Groupon is clearing out the Product(RED) colorway for 30-pin iPhones for $25 with free shipping. If you want a black version or simply prefer shopping through Amazon, a third-party retailer over at Amazon has them for $30 with Prime shipping. Sorry iPhone 5 users, this deal is for 30-pin chargers only—that's why it's so cheap. It's a small price for a tiny piece of mind. [Groupon | Amazon]

Note: Android users and folks who need a MicroUSB charger, you're not totally out of luck. Amazon's selling a MicroUSB version, but they're out of stock at the moment. You can still buy it at $30 and you'll get it shipped when it's back in stock. Go here and choose "more buying choices" from the right side. [Amazon]

Nope.

Tablets

Yes, while on the surface a $180 refurbished Nexus 7 seems like a terrible deal when you compare it to a new one at $200 from Google Play, it's actually a sneaky good deal on a tablet that's already an excellent value. Google Play tacks on between $20-$30 for shipping charges and tax. The refurb that's on 1 Sale a Day doesn't require tax for most states, and shipping's free. From New York, the 1 Sale a Day offer saves me $52. [1 Sale a Day]
